quark    音标拼音: [kw'ɑrk]
n. 一种假设的素粒子

一种假设的素粒子

quark
n 1: (physics) hypothetical truly fundamental particle in mesons
and baryons; there are supposed to be six flavors of quarks
(and their antiquarks), which come in pairs; each has an
electric charge of 2/3 or -1/3; "quarks have not been
observed directly but theoretical predictions based on
their existence have been confirmed experimentally"
2: fresh unripened cheese of a smooth texture made from
pasteurized milk, a starter, and rennet [synonym: {quark cheese},
{quark}]

  • Whats inside a quark? | Questions | Naked Scientists
    If you could break open a quark, what would you find inside?
  • HOW DOES AN UP QUARK TURN INTO A DOWN QUARK?
    An imaginary picture of the hydrogen atom, the proton is composed of two red up quarks and one blue down quark with the electron being a yellow point What do you suppose the code is that mixes the electron with one of the red quarks turning into a blue quark and thus a neutron?
  • What do strange quarks do? | Naked Science Forum
    Atoms are constructed of two types of elementary particles: electrons and quarks Electrons occupy a space that surrounds an atom's nucleus Each electron has an electrical charge of -1 Quarks make up protons and neutrons, which, in turn, make up an atom's nucleus Each proton and each neutron contains three quarks A quark is a fast-moving point of energy There are several varieties of
  • Why do quarks, last less time, outside the composites particles they . . .
    This may add a quark or two that may only exist under these unique lab conditions This intermediate and unstable state could explain the short life The properties of materials within nature show both a temperature and pressure dependency
  • Tetraquarks: new configurations of subatomic particles discovered
    Researchers using the Large Hadron Collider at CERN say they’ve recently discovered a new exotic form of subatomic particles called tetraquarks They exist for just fractions of a second, so they’re hard to spot and study But, luckily, University of Cambridge physicist Harry Cliff, is working on the experiment that discovered them, as he described to Chris Smith
  • Whats the smallest particle we can detect? | Science Questions
    And that’s called a cross section in particle physics In that case, something like a quark, which is the constituent of a proton or a neutron - very, very very, tiny I’m going to quote John Butterworth, who’s a Professor at UCL, who said “it’s about 43 billion billionths of a centimetre ” So absolutely incredibly tiny
  • If black holes stops time does white hole accelerate time?
    It could be an imbalance in the distribution of quark charge This repulsive effect would still be operating under the influence of extreme time dilation In the frame of reference of the white hole this would be undetectable as proper time would be unaffected
  • Structure of electrons, quarks and gluons; preon, preons
    Re: Structure of electron, quark and gluon, preon, preons « Reply #2 on: 03 02 2023 07:52:58 » the paragraph supplementing the text from the first post, is from 2019: A more careful analysis of the galactical model leads to the conclusion that there are more types of particles of the right type
  • Why dont atoms melt? | Page 1 | Naked Science Forum
    As the temperature and density rises atoms can become states of matter known as plasma, (ordinary star material) neutronium (neutron star material) quarkonium (quark star material) This latter state is currently hypothetical and as yet unobserved but seems quite likely
  • How do we measure the energy of a photon?
    Quark inherits from Particle, and specific quark types (UpQuark and DownQuark) inherit from Quark Fermion inherits from Particle Baryon inherits from Fermion and contains a list of quarks Proton inherits from Baryon, populates its list of quarks, and calculates its charge, spin, and mass
